Yes, you will need to know how much to serve each horse a
day. You will also need to feed more meals per day. I have the
same situation here ~ 3 ponies that are IR/one is PPID. Its just
easier to feed them in their stalls before turn out. I also rotate a
dry lot with a ‘track’. When they are on the track they wear muzzles
sealed shut because there is grass on it.
One thing to consider is a trial with the a new horse.
What if they don’t get along? What if one is a bully and chases the
weaker one away from food? You could feed one on the track and feed
the other one in the ‘’ring’’ inside the track. I use the ring for one and
the track for the other. The 3rd pony gets the drylot. I
am constantly rotating!
Here is one solution that you might be able to do at a boarding
facility. Ask the owner if you can make a track inside the
drylot using step in electric posts. You could have one or two
strands of rope or tape with a gate latch. You could use a
reasonable priced solar charger. Get a roll of coated wire to bury
in the ground to the track. You could build this in a
few hours and it wouldn’t cost much.
One way to monitor your mare’s hay servings is to use
polyhaynets. Divide the hay by the feedings you decide to do
each day. Lay a stall mat to serve on or build a hay tree.
When it comes to feeding I make sure my ponies are
seperated. Don’t forget buckets of water and shade/wind
break. You could design a hay tree that is a wind break, has a
roof and eyebolts to hold the hay net, water bucket and feed
bucket!
Hope this gets you thinking of possiblities. It CAN be
done!
